SPANNING-FRAME.

Specification of Letters Patent. Patented Feb. 15, 1916.

Application and June s, 1914, Ser'ialNo. 843,897. Renewed August 4-, 1915. Serial No. 43,708.

To all whom it may concern Be it known that I, Kenn F. Jnrsnu, a subject of the King of Swedemand a resident of South River, in "the county of Middlesex and iE-tatc of iiew Jersey, have invented certain new dents in vpanningFrames, of which the following is a specification.

My invention relates to improvements in,

frames for spanning pieces of fabric, such for example, as handkerchiefs, for the purpose of holding the fabric while it'is" being embroidered or otherwise worked upon.

In the embroidering of handkerchiefs and the like in large numbers, it is't'he custom to mount a considerable numberof pieces of fabric in a suitable frame, termed a spanning frame, the frame being so con structed as to hold straight and practically rigid the particular portion of each one of the pieces of fabric which are to be" embroidered or otherwise worked upon, and then the frame, or a plurality of such frames having the pieces of fabric spanned therein, is set within a suitable embroidery machine, and by the operation of such machine the same ornamental figure or other device is stitched upon each of the pieces of fabric in such frame or frames, simultaneously. I V

The spanning frameforming the subject matter of the present application is particu larly adapted for holding the fabric near the corner; as, for example, for the working of an initial or other ornamentation near the corner; but is likewise adapted for holding the fabric at any other points than near the corners.

li Iy invention consists in the novel spanning devices employed, in the novel means employed for locking the spanning devices, in the novel means employed forgaging the point at which the fabric is to be clamped, and in varlous other features hereinafter.

particularly pointed out described and more in the appended claims. a I

The objects of my invention are to improve and simplify spanning devices; to provide improved and simplified means for locking the spanning devicestogethe'r' and for facilitating the unlocking of such spanning devices; to provide simple and readily adjustable means for gaging the point" at which the fabric is tobe spanned; and in general to produce a spanning device which and useful Improve is simple in construction, and capable of being operated with ease and rapidity.

I will'now proceed to describe my inven .tion with reference to the accompanying drawings, and will then point out the novel features in claims; I

In said drawings: Figure 1 shows a fragmentary top view of a-portion of a spanning frame employing my invention. Fig. :2 shows a transverse section thereof on the line m-m of Fig. 1; and Fig. 3: shows a fragmentary bottom view. Figs. 17 inclusive are detail views of parts of the spring clamp preferably employed, Fig. a being an elevation and partial longitudinal section of the pin of said clamp, Fig. 5 an elevation of the sleeve of said clamp, Fig. 6 an elevation ofithe endof one of the members3 carrying the bushing 12, and Fig.7 a longitudinalsection of the spring gripping ,device let.

My improved spanning frame comprises a plate 1, commonly and preferably formed of ametal which is at once rigid, light, not likely to soil fabric, and free from objec tionable tendency to oxidationror' corrosion Monelfmetal and similar alloys are suitable for thepurpose'), such plate'proaided at suitable intervals with suitable spanning apertures 2', preferably slightly apered as indicated in Fig. 2; and a plurality of light members 3, hinged or otherwise movably secured to the plate 1, at one end, and provided with annular flanges 4 adapted to enter the spanning apertures 2 of plate 1, as indicated particularly 2, and also provided with suitable means for fastening down their free ends; for example, the spring clamp hereinafter described. These members 3 are also, preferably, formed of metal, and in the construction shown I ha'vevindicated these members 3 as hinged-each at one end, to the plate 1,

in that said members 3 are hingedto' hinge blocks 5 secured to plate 1 bygb'eing recessed partly intolsaid plate and by means of screws 6. The members 3 are preferably somewhat s'pringy or resilient. surface of each annular flange i conforms, preferably, somewhat closely to the aperture into which it is adapted to fit, with ust enough clearance from the sides of such aperture to permit the" tight claniplng of the fabric between the outside of the flange 42 1 1 the ides c uch p re sincerthe flange is annular, the embroidery needle or needles may work through the open center o such flange so embroidering the desired figure on the fabric so held.

Various means may be employed for fas ing 12 and between the free end '7 of menr,

her 3, and the head 9 of the pin 8; and a clamping spring 14c secured to the lower side of the plate 1 and having in it an aperture for the passage of the pin 8. The aperture in the spring 14: is only very slightly large than the pin 8, and is set at a very slight angle to the axis of the pin 8, so that it tends to clamp said pin 8 and hold it 'frictionally against upward motion.

with a The plate 1 is further provided headed releasing pin, 15, for each spring 14, said pin working through a suitable aperture in the plate 1, having at its upper end a convenient head 16 and having at its lower end another head 17 resting against the end of the plate 1%. It will be seenthat, with the parts in the position shown in Fig. slight pressure upon the head 9 of the pin 8 will force that pin down, through'the aperture in the spring 11, and that such spring ill hold the pin 8, frictionally, against return; but that pressure upon the head 16 of the releasing pin 15 will depress the spring 14+ sufliciently to bring the axis of its aperture substantially coincident with the axis of the pin 8, thereby permitting the spring 13 (which spring was compressedby pressing the pin 8 downward) to force pin 8 upward. In practice, when the releasing button 16 is pressed, the spring 13. aided by the spring action of member 3, forces the pin 8 up far enough to clear the spring 14: altogether.

The sleeve 10 forms a guide for the pin 8, and also forms a stop to limit the extent of depression of that pin. Said sleeve 10 has in it a slot 18 in which. works a pin 19' projecting from pin 8, whereby when the corresponding member. 3 is raised, said sleeve 10 is prevented from dropping off the pin 8. The bushing 12 centralizes the spring 13,-and also forms means for communicating downward motion of the head 9 of pin 8 to the free end 7 of member 3.

The spring clamping means just described forms a very compact, easily operated, easily released, and positive friction lock or clamp for the member 3.

Asa convenient means for gaging the proper position of the pieces of fabric, 1 have provided the plate 1 with a gage plate 20, having in it V-shapedrecesses 21 adapted to receive the corners of the fabric; said gage pass screws 23 by which the gage plate is secured to the plate 1. It will be seen that the screws 23 and slots 22 permit the gage plate to be set at. various distances from the apertures 2.

Themanner of using the. improved span-- ning frame will now be apparent. At the right ofFig. 1 Ihave shown a piece of fabric in place'in the frame and held between the sides of one of the apertures 2 and the flange 1 of the corresponding memher 3. In spanning such; a piece of fabric, the corner of the fabric is set into the corres ondin V-shaped recess of the "a e" A G D.

plate 20, with the fabric spread across the aperture 2, and theremainder of the fabric laid to one side of the hole in plate 1 through whichthe pin 8 is to pass; the member 3 is thenbrought down, its flange i pressing the fabric against the sides of the aperture 2,. and stretching. the fabric tightly; the member '3 being then secured by pressing down the pin 8, such pinbeing held when so pressed down, by the clamping spring 14. Other pieces of fabric are spanned in the same manner, under-successive members 3. Then it is desired to release the pieces of fabric from the spanning frame, the several releasing buttons 16 are pressed, and as each button is pressed its corresponding' member, 3 flies upward, releasing thefabric.

The degree of obliquity of the apertures in spring ll through which the pin 8 passes, with reference to the axis of that pin, is so slight that I have indicated it in Fig. 7 by showing in. dotted lines the'axis of said on opposite sides of the correspondingspanning apertures.
